Abstract
The present invention relates to the process for the scalable production of FeO/Fe, Sn & Zn doped graphene nanosheets from a naturally abundant seaweed resources such asand. The granules remained after the recovery of liquid juice from the fresh seaweeds were utilized as a raw material and a deep eutectic solvents (DESs) generated by the complexation of choline chloride and FeCl, ZnCland SnClwere employed as template as well as catalyst for the production graphene nanosheets functionalized with metals. Pyrolysis of the mixture of seaweed granules and DES at 700-900° C. under 95% Nand 5% Hatmosphere resulted formation of metal doped graphene sheets with high surface area (120-225 m·g) and high electrical conductivity 2384 mS·mto 2400 mS·m. The nanosheets thus obtained could remove substantial amount of fluoride from fluoride contaminated drinking water (95-98%).
